March 2009 – Torus Power’s Power Isolation Units (PIUs) combine surge suppression with massive toroidal transformers to provide AC power conditioning and protection from voltage surges.

The RM 20 uses a single 2400VA toroidal transformer to supply 120V and 20 amperes to the 10 AC outlets on its rear panel. It has a 20A circuit breaker for its On/Off switch and uses a 14AWG detachable AC cord rated at 15A/125V. “The PIU greatly enhanced subtle details of tone, timbre, and imaging when dynamics were extreme or volume was loud,” said LG.
